IMPROVEMENT IN CIGAR-PIPES.

Specification forming part of Letters Patent No. 214,164, dated April 8,1879; application filed February 14, 1879.

To all whom it mag concern:

Be it known that I, ISAAC P. MAXWELL, of Baltimore city, State ofMaryland, have invented certain new and useful Improvements inCigar-Pipes; and I hereby declare the same to be fully, clearly, andexactly described as follows, reference being had to the accompanyin gdrawing, in which a ciganpipe is illustrated embodying my presentinvention.

In devices of this class a difficulty has heretofore been met which itis the main design of my invention to obviate. Owing to the neoessarilysmall bore of the pipe the area of combustion is so limited that thefire is extremely likely to go out-a result which is mainly attributableto the presence of the products of combustion, which are highly chargedwith carbonic acid. In a word, the device operates upon the principle ofa chemical fire-extinguisher to put out the light.

My present invention consists in certain peculiarities of constructionof the cigar-pipe not here necessary to enumerate, as they are made thesubject of claims based on the following description.

In the accompanying drawing, A represents the imitation cigar, which ismade of wood or other suitable material, stained and grained to presentthe appearance of an ordinary cigar. It is bored out substantially asshown in dotted lines 0, and is provided at its end with abushin g,b,preferably of metal,threaded to receive the end of the imitation asha. This latter is made of pumice-stone, which exactly resemblestobacco-ash, mounted upon a metallic tube, which is threaded at b toengage with the bushing b. The natural porosity of the pumice-stone Willgenerally aflord sufficient draft; butif not holes a are made therein,as shown. The otherend of the cigar is formed with a spiral groove inexaggerated imitation of the curled end of an ordinary cigar-wrapper,the points at d serving to afford a convenient holdingplace for theteeth at various points on the cigar-tip.

Along the line of the imitation wrapper fine holes 0 c are made to admitair to the interior of the cigar.

In operation a piece of cigarette-paper is inserted in the device, whichis then filled with tobacco in the usual way and lit, the ash abeingfinally screwed on. As the contents are consumed, the holes 0 c areuncovered seriatim, admitting air to the interior of the device, andpreventing the light from being extinguished by the products ofcombustion.

When the device is removed from the mouth the smoke escapes through theminute perforations in the pumice-stone precisely as it escapes throughthe ash of an ordinary cigar, and not in the series of definite andwell-defined streams that escape from cigar-pipes as heretofore made.

The peculiar construction of the mouth-piece is extremely grateful tothe user. It affords a series of holding-places for the teeth at variousdistances apart, and enables the user to change as the jaws becomefatigued from the strain in one position.

What I claim as new is 1. A cigar-pipe having a spiral indentation uponits mouth-piece, as set forth.

2. A cigar-pipe having a conical or tapering mouth-piece spirallyindented, substantially as set forth.

3. A cigar-pipe having a pumice-stone tip, substantially as described.

4. The cigar-pipe herein described, having a pumice-stone tip adaptedfor insertion in its iorward end and a spirally-grooved mouth piece,substantially as described.
